Where and how can I find and download Android 1.5 source code?

Question

我在哪里以及如何找到并下载Android 1.5源代码？

Answer 1

To get a specific branch of the android source, you use the repo just like you would to get the latest version. After you follow the instructions on the info for setting up the machine in the links that were supplied by the other answers, you would run

repo init -u https://android.googlesource.com/platform/manifest -b cupcake 

That will pull the 1.5 version of the source code.

Answer 2

http://source.android.com - The homepage for the Android source
https://android.googlesource.com - The homepage for the actual Android source code.

http://source.android.com/source/download.html - Instructions for downloading the source code.

Answer 3

I'd imagine you would get it from the android git repository?
Web interface: https://android.googlesource.com/
SDK: http://developer.android.com/sdk/index.html

Details on how to access it:
https://source.android.com/source/downloading

Note, the repository contains the current version so the above is likely uninteresting to you.
I found this though:
